GRAIN-ELEVATOR FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 369,396, dated September 6, 1887.

Application filed June 8, 1886.

To (LZZ whom it may concern:

Be it known that I, EDWIN B. (Borrow, a citizen of the United States, residing at Volinia, Cass county, Michigan, (post-office address, Decatur, county of Van Buren, State of Michigan,)haveinvented a new and useful Grain-Elevator for Harvesters, of which the following is a specification.

This invention relates to that class of grainclcvators which consist of two parallel endless belts, used in connection with that class of harvesters in which the grain, after being cut, falls upon a horizontal carrier in the rear of the cut-- ting apparatus, which carrier takes the grain laterally to the mouth of the elevator, from whence it is carried up to the binding-table or mechanism by the two belts, the grain being carried up between said belts.

The object of the invention is to effect certain improvements in the side boards'of the elevator, designed to simplify construction and to increase the utility.

In the accompanying drawings, forming a partof this specification, Figure 1 is an elevation of the oblique elevator and the horizontal graincarrier. Figs. 2 and 3 are elevations of equivalents, parts being broken away; and Fig. 4 is a detail, with parts broken away, of Fig. 3 enlarged.

Referring to theletters marked on the drawings, B is the side board of the upper beltframe, bearing one roller, 2 at the top and two at the bottom. Of course there is another side board opposite to this tosupport the other end of the rollers.

The coininonlyemployed lower belt, 0 0, (running parallel with the ordinary belt, a a, used in such elevators) runs on rollers f f, which rollers of course have suitable bearings at each end, the other end not being here shown. The horizontal carrier-belt c a 0n rollers ti is in the rear of the cutting mechanism.

The frame of the belt a a is located above belt 0, the two sides being placed to form an oblique angle, extending from a point a little above the carrier at u up to the binding-table or mechanism above.

The binding mechanism, cutting device, the ordinary frame, and the other parts of a reaper are not herein shown. Those skilled in the art will readily understand the use of the ele vator.

In Fig. 1 the side boards, B, are made of one piece of wood, a pointed piece being cut out of the lower portion, leaving the upper arm, A. This arm A, thus integral with the side board, is elastic and can readily be sprung nearer the other arm, which bears the lower roller of the side board. By this means the roller in the lower end of the clastic arm A is carried away from or brought nearer to the other roller and held in the desired position by the strap 1', having adj ustingslots in the ends, through which slots thebolts pass which hold the strap to the arms. The object of changing thelocat-iou of saidroller is to make the mouth to the elevator larger or smaller, according to the nature of the grain, whether it is straight or lodged. This adjustment is simple, the side board cheap and not likely to get out of order, like such parts in elevators heretofore used, and the adjustment of said roller is effected without changing the position of the lower roller in the board B or the lower roller nearest to the belt 0. If a larger throat to the elevator is desired, or a smaller one, the frame of the belt a a is raised or lowered, and thus both the lower rollers of the side boards are raised or lowered the same distance.

In Fig. 2 the arm A is elastic metal, rigidly held at the top by the bolt 3 which secures it to the side B of the frame. The same adjustable strap, 1', is employed as in Fig. 1.

In Fig. 8 the adjusting is accomplished by slotting the upper end of the bar A at m, Fig. 4, the bolt y being in said slot. The strap or bar r in Fig. 3 being pivoted to the arm A of the side board at the end of said bar,when the arm is carried up or down the lower end is carried out or in, thus effecting the adjustment.

The parts which are lettered alike in the different figures have like functions. In Figs. 2 and 3 the lower end of the metal arm A is turned under,and in the bend a bearing-block, D, is bolted. The side boards are hollowed out on top from the ends, the eenterbeing lower than the ends where the rollers are located,to prevent the upper belt from rubbing the upper edges of the board.

The tendency of the upper belt is to sag by its own weight, and if the upper edge of the board is cut out hollow,as shown at 2, so as to make the edge of the boardlower than the end rollers and especially lower in the longitudinal center between the ends where the belt sags the most, said belt will not rub the edge of the board at any point.

Having thus described my invention, what I claim as new is In a grain-elevator of the style described,the belt-frame having side boards forked at their lower ends to form arms for the belt-rollers, the upper one of said arms being elastic, and

the adj usting-strap, whereby said elastic arms may be sprung farther away from the lower I5 arm or sprung nearer to the latter arm and be held in the desired position by said strap, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two 20 witnesses.
